This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
the gnu libobjc rather than the NeXT one. I do not understand objc
so I don't know the implications of this, but the gcc-2.7.2 libobjc is
built with this.
bsd.obj.mk. Also, a make target called objwarn checks to see
if ${.OBJDIR} != ${.CURDIR} and ${.OBJDIR} != ${CANONICALOBJDIR}
and outputs a warning. (No warning for the latter if MAKEOBJDIR or MAKEOBJDIRP
REFIX is set). objwarn is called from all targets in bsd.prog.mk, bsd.kmod.mk,
and bsd.lib.mk.

eliminates many local symbols that could not be removed by the "ld -r -x"
steps on the individual object files. It makes shared libraries
substantially smaller -- almost 11%, in the case of libc.so.3.0.
*Really* strip out unused local symbols from shared objects.
This was a typo on my part caused by an assumption that the profiled
libraries stripped symbols that same way as the non-profiled libraries.
Cut-n-Paste strikes again.

`depend' wasn't supported. This seems to have only broken `make depend'
in gnu/usr.bin/ld.
bsd.prog.mk:
Build the man pages in ${MANDEPEND} at build time.
Define SHLIBDIR?= ${LIBDIR} and install shared libraries in
${DESTDIR}${SHLIBDIR} instead of in ${DESTDIR}${LIBDIR}.
SHLIBDIR may be defined in /etc/make.conf to override the
default of /usr/lib (I use /lib). Other changes are required
for non-default shared library directories to actually work
(ld* and crtso have too many hard-coded paths).

RANTOUCH may be defined in /etc/make.conf as
`${ECHO} skipping ${RANLIB} -t' to help stop `make install' from
changing the timestamps on unchanged libraries, thus making the
uninstalled binaries appear to be out of date... Other changes
are required to stop install from clobbering the timestamps.
put the stuff into the right "distribution". As default things end up
in "bindist".
Normal (ie: most) makefiles know naught of this.
More commits will follow, which will direct various parts of the tree
into the distribution we want them in.
Some of the grief of being release-engineer is supposed to go away with this.
PRECIOUSLIB causes the shared library to be installed with the system
immutable flag (schg) set. (You can add other flags for shared-library
installation by modifying SHLINSTALLFLAGS.)
INTERNALLIB disables the generation of non-shared versions of the library.
This may be of use for programs like Taylor UUCP and GCC which have large
internal libraries shared among a number of programs.
Makefiles.
DANGER WILL ROBINSON!
This will cause repeat installs of certain programs, such as `init' and
`rcp', to fail unless one of the two conditions is met:
1) You are in single-user mode.
2) Your security level is set to 0 or -1.
If you have compiled a kernel from the latest sources, your kernel
security level is set to -1 by default, which will keep `init' from
fiddling with it. You can increase it, but not decrease it, from the
command line with the command `sysctl -w kern.securelevel=<new value>'.
I believe that -1 is the most appropriate value to use while we are still
developing the code, although when we ship it should be changed back to 0.
See init(8) for more information.
